Description

TECHNICAL FIELD

[0001] The application relates to the technical field of door and window hardware, in particular to an angle code for profile connection. BACKGROUND

[0002] The connection of door and window profiles is usually fixed and connected by means of an angle code. Most of the existing door and window angle codes are small and are inserted into the profiles by meansing to connect the vertical frame profile and the horizontal frame profile. Although this connection method can meet the installation requirements to a certain extent, the overall structure has low strength due to the small size of the angle code and the limited connection points, and problems such as loosening, deformation or unstable connection are prone to occur during long-term use.

[0003] Specifically, the mechanical properties of the existing angle code are relatively dispersed when the profiles are connected, and the external force received by the horizontal frame and the vertical frame profile cannot be uniformly distributed and borne. In particular, when facing the stress impact generated by the wind pressure, opening and closing of the door and window and the long-term influence of the external environment, the stability and durability of the connecting piece are obviously insufficient. In addition, during installation, multiple angle codes need to be inserted into the profiles one by one, which not only increases the complexity of the installation process, but also easily leads to error accumulation. Combined with the above-mentioned low bearing capacity and easy deformation, it directly affects the sealing performance of the door and window under long-term use. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the bearing capacity of the angle code and simplify the installation process of the angle code, the application provides an angle code for profile connection.

[0005] The application provides an angle code for profile connection, which adopts the following technical scheme:

[0006] An angle code for profile connection, comprising an L-shaped connecting seat, the L-shaped connecting seat is provided with a connecting part on both sides, and the L-shaped connecting seat is provided with a plug-in column at both ends, the plug-in column at one end of the connecting seat is used for inserting into the profile of the door and window horizontal frame, the plug-in column at the other end of the connecting seat is used for inserting into the profile of the door and window vertical frame, the two connecting parts are respectively connected with the end part of the door and window outer frame profile and the end part of the door and window inner frame profile, and the total width of the connecting seat and the two connecting parts is not less than the width of the window frame.

[0007] By adopting the above technical scheme, when installing, only the inner and outer profiles of the door and window horizontal frame and the inner and outer profiles of the door and window vertical frame corresponding to the multiple plug-in columns need to be inserted, so that the connection of the profiles can be completed, the installation process is simplified, the steps of inserting the angle code are reduced, the installation efficiency is improved, and the error accumulation problem prone to occur during installation of multiple angle codes is avoided.

[0008] The L-shaped connecting seat and the plug-in column provide greater contact area and supporting force, the stability and carrying capacity of the structure are significantly improved, and the structure is more suitable for large-weight doors and windows, can effectively cope with wind pressure, impact force generated by opening and closing of large-weight doors and windows, effectively avoids problems such as connection loosening and deformation after long-term use, prolongs the service life of the door and window structure, and enhances the durability of the connecting piece.

[0009] Optionally, the connecting part is a rectangular plate.

[0010] By adopting the above technical scheme, the end of the profile is usually cut into a 45-degree bevel to realize the splicing of the horizontal frame profile and the vertical frame profile. However, the 45-degree bevel processing requires high precision, and is easily affected by factors such as cutting equipment precision and operation angle, resulting in processing errors. Therefore, by using the rectangular plate connecting part, the end of the profile can be directly cut into a 90-degree right angle without complex bevel cutting. The right-angle cutting is simpler in operation and easier to control in precision, so the rectangular plate connecting part not only facilitates profile processing, but also reduces splicing errors and improves installation precision.

[0011] Optionally, the L-shaped connecting seat is provided with a reinforcing part on both sides, the reinforcing part extends out of both ends of the connecting seat, and the reinforcing part is attached to the side wall of the profile when the profile is connected to the connecting part.

[0012] By adopting the above technical scheme, the reinforcing part extends out of both sides of the L-shaped connecting seat and is attached to the side wall of the profile, forming a structure similar to a reinforcing rib, which can effectively improve the structural rigidity and strength of the whole corner code. This design makes the corner code not only rely on the support of the plug-in column when bearing external force, but also rely on the close attachment of the reinforcing part and the profile side wall to increase the area of the connection point, disperse the stress, and significantly improve the compression resistance, shear resistance and bending resistance of the corner code.

[0013] And the attachment design of the reinforcing part and the profile side wall can provide better alignment and positioning effect during splicing, so that the tightness between the profile and the connecting part is higher during installation.

[0014] Optionally, the plug-in column is provided with a first glue injection groove, the L-shaped connecting seat is provided with a second glue injection groove on the end face, the plug-in column is further provided with a glue injection hole in communication with the first glue injection groove, the first glue injection groove and the second glue injection groove are in communication, the inner wall of the first glue injection groove, the inner wall of the profile insertion hole, the glue injection hole, the second glue injection groove and the end face of the profile form a glue injection channel, and the plug-in column is provided with a plugging head for sealing both ends of the glue injection channel, and the plugging head is matched with the profile insertion hole.

[0015] By adopting the technical scheme, the waterproof glue is injected into the glue injection hole, the first glue injection groove and the second glue injection groove through the hole on the profile, forming a closed waterproof channel. This makes the waterproof glue fill the gap between the profile and the corner code, achieving good sealing effect.

[0016] The plug-in head is matched with the profile hole, can seal both ends of the glue injection channel, prevent the waterproof glue from flowing from the hole to the middle of the profile or other unnecessary areas during injection, and avoid waste of too much glue.

[0017] Optionally, the L-shaped connecting seat, the plug-in column and the connecting plate are integrally formed by die casting, and the plug-in head is detachably connected with the plug-in column.

[0018] By adopting the technical scheme, the die casting integrally formed process can make the L-shaped connecting seat, the plug-in column and the connecting plate into a complete structure during manufacturing. This integrally formed manner avoids splicing or welding between parts, eliminates stress concentration and weak points that may occur at the joint parts. The strength and impact resistance of the overall structure are thus significantly improved, and multiple parts assembly is not required, improving production efficiency.

[0019] Since the cross-sectional size of the plug-in head is larger than that of the plug-in column, if the plug-in head is directly integrally formed by die casting, demolding problems may occur during die casting. Therefore, the plug-in head is designed to be detachably connected, and the plug-in head is assembled after the other parts are die cast, which can simplify the mold design.

[0020] Optionally, the first glue injection groove includes a first groove and a second groove, the first groove is arranged on one side of the plug-in column facing the door and window frame, the second groove is arranged on the side of the plug-in column away from the door and window frame, the first groove and the second groove are arranged along the length direction of the plug-in column, the glue injection hole is in communication with the first groove and the second groove, and the first groove is in communication with the second glue injection groove.

[0021] By adopting the technical scheme, a specific design of the first glue injection groove is provided. By arranging the first groove and the second groove on the two sides of the plug-in column respectively, the glue can be more uniformly distributed on the front and back surfaces of the plug-in column during glue injection, ensuring that a relatively uniform glue layer is formed in the entire connecting area. This design avoids the glue being concentrated on one side, improving the sealing performance and connection firmness of the entire structure.

[0022] Optionally, the plug-in column is provided with a guide arc groove in communication with the first glue injection groove, the guide arc groove penetrates to the end of the plug-in column away from the L-shaped connecting seat, the end face of the plug-in column away from the L-shaped connecting seat is provided as a first tapered guide surface, the plug-in head is connected with a plug-in part, one side of the plug-in part is attached to the tapered guide surface, the plug-in part is tightly matched with the first glue injection groove, the end of the plug-in column away from the L-shaped connecting seat can be inserted into the plug-in head, and the first tapered guide surface is attached to the inside of the plug-in head.

[0023] By adopting the above technical scheme, the tight matching of the plug-in part and the first glue injection groove can ensure the stable installation of the plug-in head, avoid the loosening or displacement of the plug-in head, and the guide arc groove and the first tapered guide surface play a guiding and positioning role, facilitating the accurate insertion of the plug-in part in the first glue injection groove.

[0024] Optionally, the end face of the plug-in head away from the plug-in column is provided as a second tapered guide surface.

[0025] By adopting the above technical scheme, the second tapered guide surface plays a guiding role, facilitating the smooth insertion of the plug-in head and the plug-in column into the profile, especially in the case of synchronous insertion of multiple plug-in columns into the profile, facilitating installation and improving installation efficiency.

[0026] Optionally, the middle part of the end face of the L-shaped connecting seat is provided with a protruding part, which separates the space between the heat insulation strip and the profile from the glue injection channel.

[0027] By adopting the above technical scheme, the protruding part is arranged in the middle part of the end face of the L-shaped connecting seat, which separates the space between the heat insulation strip and the profile from the glue injection channel, effectively preventing the glue from flowing into the gap between the heat insulation strip and the profile during glue injection, and avoiding the glue from entering unnecessary areas.

[0028] Optionally, the reinforcing part is an L-shaped reinforcing plate, and the two reinforcing parts are oppositely arranged and attached to the inner wall of the profile.

[0029] In summary, the present application has the following at least one beneficial technical effect:

[0030] 1. The corner code provides a larger contact area and support force, the stability and carrying capacity of the structure are significantly improved, and it is more suitable for heavy doors and windows, can effectively cope with wind pressure, impact force generated by opening and closing of heavy doors and windows, effectively avoids problems such as loosening and deformation after long-term use, prolongs the service life of the door and window structure, and enhances the durability of the connecting part.

[0031] 2. The rectangular plate-shaped connecting part can directly cut the end of the profile into a 90-degree right angle without complex bevel cutting. The right-angle cutting is simpler in operation and easier to control in precision. Therefore, the rectangular plate-shaped connecting part not only facilitates the profile processing, but also reduces the splicing error and improves the installation precision;

[0032] 3. When installing, only the inner and outer profiles of the door and window horizontal frame and the inner and outer profiles of the door and window vertical frame corresponding to the plurality of insertion columns need to be inserted, so that the connection of the profiles is completed, the installation process is simplified, the steps of the corner code insertion are reduced, the installation efficiency is improved, and the error accumulation problem easily caused by multiple corner code installation is avoided;

[0033] 4. The reinforcing part is formed by extending from both sides of the L-shaped connecting seat and abutting with the side wall of the profile, forming a structure similar to a reinforcing rib, which can effectively improve the structural rigidity and strength of the corner code as a whole, and the abutting design of the reinforcing part and the profile side wall can provide better alignment and positioning effect during splicing, so that the tightness between the profile and the connecting part during installation is higher;

[0034] 5. The process of die-casting integrated molding can make the L-shaped connecting seat, the insertion column and the connecting plate become a complete structure during manufacturing.
